To all whom t may-conocia: 'Be it known that I, HENRY H. J oHnsoN, a citizen of the United States, residmg at Avoca, in the county'of Pottawattamie, Statev of Iowa, have invented certain new and use- 'ful .Improvementsin Anf-Ships; and I do hereby' declare the following to be a full,-

' clear, and exact description of the invention,

. ing the speed of the en provide mechanismv for such as will enable others skilled in the art to.

which it appertains to make ,and lisethesame.

This invention relates to air-ships. i ,'Onewobject of the invention resides in an improved speedmech'anism.

Another object ofthe invention resides in i "the provision of means whereby the.speed 'of he ship may be increased or slackened durinvv the normal rotation ofthe enginefshaft, ,wich latter f may` be rotated continuously in one direction withoutin'creasing or slack- A still further object tilflthe invention is to. guiding -or steering the ship without the use .of a rudder.

With these andn other objects in view thev present invention consistsinethe combination and arrangement of parts,"as will be hereinafter more fully` described, shown in theac companying drawings, and particularly pointblades;

ed out 'in the appended claims, it being understood that changes in the form, proportion, size, andminor details maybe made within the scope of the claims without departing from the spirit or'sacriiicing any of the advanta esfof theinvention. f

In t e drawings, Figure 1 is a sideelevation of a structure embodying my invention."

Fig. 2 is a top plan view of the propeller'- Fig. 3 is a detail view'of one of the propeller-blades, illustratin the manner in which the latter is mounted forpivotal movement. Fig. 4 isan end View of one of thesleeves mounted for sliding movement upon the4 propeller-shaft. Fig. '5 is a modified form of propeller-blade. Fig. 6 is aqsectionalview. 1, 'L

Referring now more particularly tothe accompanying `drawings, the reference character 1 designates an upright propeller-shaft, which is preferabl tion and connected7 at its lower end'to an en- (Not shown.) i Looselymounted .upon the propeller-shaft 1, near the upper end thereof, is a collar 2, having a rectangularshaped bore 3, whereby it may be slidably mounted upon the rectangular-shaped prorectangular in cross-secpeller-shaft, the collar havingVV upper and lower fianges `4 and 5, respectively. Embracing this collar 2 intermediate its flanges 4 and 5 is an iron or other strap 6, Whose free ends receive between them the head 7 of the enlarged portion 8 of the -downwardly-dilower wheel 17 being designed to bear against the under face thereof, as clearly shown.

. Mounted upon the propeller-shaft 1, near the lower end thereof, is a second collar 18, having upper and lower flanges 19 and 20, respectively, there being a. secondiron or other strap 21 embracing the second collar glane as the aforesaid iron or other strap 6. etween the inner faces of the free ends of the second strap 21 the lower end of the arm 9 is pivotally connected through-the instrumentality of 4a suitabley pivot-pin 22, the second collar 18 and its connection'21 bein slidable upon the propeller-shaft l1 through the instrumentality of a lever' 23, fulcrumed, as at 24, upon the upper end of the su port 25, the inner end of the.said lever 23j' eing pivotally connected, by means ofa suitable pivot-pin'or the like 26, between-the ends of the 'aforesaid free ends of the iron or other .strap 18, there being ardog 27 associated with the lever 23 for engagement in the rack 28 whereby thelever may hold the aforesaid collars 2 and 18 in vadjusted positions upon the propeller-shaft 1, there being a suitable link connection 29 between the said dog 27 and the pivoted hand-lever 30.

rovide with' a collar ars 31 3.1 and 32 32', arranged at rightan les to. each other. Each bar is provided wit a suitable propeller-blade 33, each blade being tion 8, immediately beneath the head 7, is a The lpper end of the tpropellflali-slhaftt1 om w c eX en pivotally connected at its under facev to its corresponding bar and having its lower edge intermediate its ends connected .by a rod 36 to the upper Harige 4 of collar 2, wherebythe upward and downward movement of collars 2 and 18 will Icorrespondingly swing each 8o between its `flanges and directed in the same I rotate with the continuously-rotating prounderstood, it is obvious that rotation of the longitudinally of the propeller-s att 1, causi throw the sleeves 2 and 18- downwardly to ing-'the lower flange 5 of the upper sleeve 2 used instead of the aforesaid wheels 12 and 17 l ars are of course reversely arranged with I complished, without slacking the speed of the blade. upon its bar-face, adjusting the angle of the blades with res ect to thehorizontal plane of the bars'. T e blades of opposite respectto each other, as usual.

It will nowbe understood that the shaft lis rotatable and that by` reason of the metangular-shaped bore of the collars 2 andlS they peller-shaft-` The iron or other straps 6 and 21 and the arm 9 bdo not rotate. This being pro eller-shaft 1 will cause the propellerk la e 33 'to rotate and that when the lever 23.is depressed u on its fulcrum 24 the collars 2 and 18 wil be raised u wardly and ing the blade 33, through the connections 35, to assume a more nearly horizontal position, thereby resulting in a slacking of speed of the air-ship. In order to present the blade 33 fully to the wind, it is simply necessary to raise the outer end of the leverv 23 to the desiredadjustment. It is obvious, too, that instead of throwing the lower edges of the blades upwardly with respect to the plane of the bars the upper edges may be thrown downwardly with respect to the plane of the. bars by the obvious manipulatlons of the sleeves 2 and 18.

- It might be stated that the lower ends ofthe rod connections 35V between the fanblades and thev upper sleeve 2 are fitted in a groove 36 in the periphery of` the flange 4 of the said collar and perforatedj for the reception of thebolts or other suitable elements 37.

Byreason of thel wheels 12 and 17 engagrnuch friction-is reduced in the rotation of thesaid sleeve, and whilethe same is not 'shown in the drawings ,for the reason that the change seems obvious, ball-bearings may be From the foregoing it willvbe seen that the propeller-blades may be adjusted at will` for the purpose of increasingor slacking speed of the ship,v and that such manipulation is ac'- engineduring the normal operation ot the latter and itspropeller-shaft 1.

In Figs. 5 and 6- of the accompanying drawings there is. shown a modied form of propeller-blade 33,-wl1ich is divided longi tudinally and centrally to .form upper and" lower portions 34 and 35', the said portions being -hingedly connected along their opposing longitudinal edges in any suitable manner,"so-that they may be hinged with respect to each other. The innerfend 33a of each blade 33 is pointed and 'the outer end thereofl is Ibifurcated, 'as at33b.` This particular y formy of blade is adapted to fold lalong theA4 line of its hinge instead of movin upon theA pivot, asin theothe'i form.l Inot er words, the upward and' downward movementof the sleeve 2" upon a continuously-rotating propell'er-shaft 1a will, by reason ofthe Aconnec- Y 1. `An air-shi comprising. a continuouslyrotating prop. e ler shaft having Vbars hconnected to itsup eil-,end 'a 'propellenblade pivotally connected at its under face to thev ends 'of each of said bars; upper and lower sleeves mounted Vfor slidable movement upon said propeller-'shaft andl for rotation therewith 3 a rod connection between;` the lower .edge of each of the propeller-blades and the upper' sleeve; an arm arranged parallel'wi-th; the

propeller-shaft a connection between they upper and lower ends of said arm, and the 1re-rj' t specti-vesleeves; the said arm havin a ref 1 cess in its inner face 5 wheels journale in the said Krecess of the arm for contact with the V upper sleeve; and a lever pivotally connected with the said connection between the lower end of the arrn, and the lower sleeve whereby the sleeves and.` arm may; be moved upf. wardly and downwardly for adjusting theV propeller-blades upon their bars to different planes with respectto the plane of said bars'.

2. An air-ship comprising a rotatable: shatt" havin bars connected to its upper endfa pro el er-bl-ade pivotally connected at its un er face to the ends of each vof said bars; upper and lower sleeves mounted for sliding Ioo movement upon said propellenshaft and for rotation therewith; a rod -connecti the lower edge of saidpropeller-blade wit the upper sleeve; an arm'arranged parallelwith the propeller-shaft; 'a strap embracing each sleeve and connected to the'respectiveend of cess in .its inner tace wheels: journaledl in the said recess of the arm' for contact with the said] arm; saidarm beingformed with a re- IIC' upper sleeve and a'lever pivotal'ly connected l. with the lower strapy whereby the sleeves and arm may be moved upwardlyand downwardly for adjusting the propeller blades upon their bars to'diiferent planes with respect tothe plane ofsaidbars.
